In a psychrometric process, the sensible heat added is 30 kJ/s and the latent heat added is 20 kJ/s. The sensible heat factor for the process will be

Answer: Option B

Sensible heat factor (s.h.f.) is the ratio of sensible heat to the total heat.
So,
$$\begin{array}{rl}& \text{s}\text{.h}\text{.f}\text{.}=\frac{30}{30+20}\\ & =\frac{30}{50}\\ & =0.6\end{array}$$
